This paper updates the 1971 Moore and Birren study using productivity of doctoral dissertations as an indicator of professional and research training in the field of aging. In comparison with the earlier study, in this current study, 1969 to 1975, there has been a marked increase in aging related titles in the social and health sciences and a drop in aging related titles in psychology with the biological sciences remaining about the same. Geographically, the three states with the largest elderly populations also have the largest productivity of dissertations in aging.
本文以博士论文的产出率作为老年学领域专业及研究培训的一项指标，对1971年穆尔和比伦的研究进行了更新。与早期研究相比，在此次涵盖1969年至1975年的研究中，社会科学与健康科学领域中与老龄化相关的论文题目显著增加，心理学领域中与老龄化相关的论文题目有所减少，而生物科学领域则基本保持不变。从地域上看，老年人口最多的三个州在老龄化研究方面的博士论文产出率也最高。
